. MEANS Eon. USE IN sTAcxING csEs.

Application illed September To all whom t may concern.:

Be it known that I, ARTHUR JAMES FISH- ER, a subject of the King of Great Britain .and Ireland, residing at Lipson Street,

Port Adelaide, State of South Australia, Commonwealth of Australia, have invented a certain new and useful Means for .Use in Stacking Cases, of which thev following is a specification.

The object of this invention is to ensure the circulation of the air all around cases of fruit or other produce which are stacked in a cool chamber, particularly in the cool` chamber of a ship.

It has been customary heretofore when stacking such cases to place below each row of cases in each layer a long plain lath or laths which permits of` some circulation,

but not a complte circulation since the air. currents can flow horizontally over the boty toms and tops only of the cases and are confined and Vchecked even then.

According to this invention all of the cases in each layer are separated one from another by a space of approximately l@ inch at the sides and ends and from the layer next above by a similar .space by `means of 'sp-acer devices each of vwhich comprises two members or arms set approximately at right angles the one to the other the one member resting upon the top of one or more of the cases and the othermember hanging between the sides or ends of adjacent cases.

v In order that the invention may be the more clearly understood I will describe thesame with reference to the accompanying drawings in whichl Fig. 1 is a perspective view showing por- 40 tion of a stack of cases provided with air spaces according to the invention.

Fig. 2 is a lanvievv,` also showing portion of a stac of cases provided with air spaces according to the invention. Fig. 3 is a view showing separately the form of the spacer device shown in position in Figs. 1 and 2.

Fig. 4 1s a similar view to Fig. 2 but showing the use of another form of spacer 59 device.

And Fi 5 is a similar view to Fig. 3 showing t e sfacer device shown in `position in Fig.

between the sides or ends'of adjacent cases. The top member A is of sufficient length only to ensure sufiicient support for the superimposed layers of cases, approximately tive inches, and the stem member B is of suiicient length to hold the device against cross movement, say 2% inches, while the width of both the members is approximately 11/2 inches.

According to the modification shown in Figs. 4 and 5 the spacer devices are made of L shape the one arm ormember A as before resting upon the top of the case and the other arm or member B hanging between the sides or ends of adjacent cases. As before the horizontal arm A, that which is placed upon the top of the case, is of suiiicient length nly to ensure, support for the superimposed layers of cases,

`say 8 or 9 inches, and the hanging arm B is of sufficient length to hold the device against cross movement, say 3 inches, while the width of both membersis approximately 11/2 inches.

The measurements specified are approximate and given by wayof example only and may be increased or decreased as may be considered desirable.

The spacer device may be made of metal or other material. For instance it may be stamped from corrugated sheet metal as shown in the drawings or it may comprise av wooden core within a sheet metal casing to provide lightness with `the necessarystren h. f

It will be evident that when the cases are stacked in the manner described and illustrated there is a space all around the top, bottom, sides and ends of each case through which the air may circulate freely, hence the contents of all the cases may be kept at the desired temperature.

' What I claim is` 1. A device for use in stacking cases of fruit or other produce comprising two members or arms set approximately at right angles the one to the other the one member being adapted to rest upon a comparatively small part o f the top of one or more cases and the other member being adapted to hang between the sides or en of adgacent cases, substantially as describe 2. A sgaer device for use in n cases of t or other produce comprising a T sha ed device -the top or cross member of whic is` adapted to rest upon a oom-` paratively small part of the tops of two adjacent cases and Vthe stem of which' i@ adapted tohang between the sides or ende of adjacent cases, substantially as deecri.
